Answers and Explanations

1.
Solve the principle of division!
Division is a much more complex calculation than addition, subtraction, or multiplication.
So, in Volume 2 of “Elementary Mathematics Division Concept Comes First,” the principle is explained using a number model before presenting the calculation method.
Using a number model, you can easily understand the process of dividing a large number first, solving the remainder, converting it to a smaller number, and then dividing.
This will also help you learn division of large numbers.


2.
As expected from a math book, it is faithful to the definitions!
All mathematics starts with definitions.
However, mathematics that is true to its definition is encountered in higher education courses, not in elementary, middle, and high school mathematics.
Originally, mathematics books were beautifully structured with a logical flow that started from definitions and led to various theorems.
〈Elementary Math Division Concept Comes First〉 aims to be a proper math book that focuses on definitions.
Starting from the definition of division, it explains in a natural flow why division must be calculated that way.

3.
Present the basis of logic!
Because mathematics is structured logically, if there is a hole in any of it, it is difficult to build new knowledge thereafter.
However, learners often neglect to study the parts that do not appear on the test.
It may be okay now, but over time, this will create gaps in your logical thinking, which will hinder your ability to learn math properly.
In order to fill in such gaps, 〈Elementary Math Division Concept Comes First〉 presents the content in a meticulous manner, presenting sound logical grounds even for the smallest details.

4.
The important thing is big! In image!
You might think a book that implements abstract mathematical concepts in a mathematical way would be difficult? Not so! This book is a "book that teaches math properly," but it explains all of this from a child's perspective.
The content is developed with interesting materials and pictures, and the intensity of the content is effectively expressed so that important information can be seen at a glance.
Until now, there has been no book that has covered division in this form and structure.
Meet Elementary Math Division Concepts Come First, which is realized with storybook-like colors, vivid concepts, and rich problems.

Free video lectures so you can study on your own!
All concept explanations are accompanied by video lectures.
Additionally, for problems that would benefit from additional explanation, we have included problem-solving lectures in QR codes.
You can view the lecture immediately by scanning the QR code without separate registration, and you can check out more reference materials by visiting www.mathbus.co.kr.
You can enjoy studying with the cheerful, refreshing, and exhilarating lectures of a former EBS teacher.

★★★ Great for students like this!
*Friends who find calculations boring* Friends who are good at finding answers, but don't know the concept when asked about it
*People who solve it well when it comes out as a formula, but get lost when it comes out as a sentence

★★★ A math book worthy of the name!!
Mathematics is often said to be beautiful because it solves problems in a clean and uncluttered way.
We are solving the division operation in the most mathematical way possible.

★★★ A book that proves that math books can be pretty too!!!
A math book with a pastel-toned layout that resembles a fairy tale has been published, unfolding mathematical concepts through illustrations.
Add fun to your studies with these pretty math books.
